BrightSource’s Ivanpah solar development is on track to become the largest solar power facility in the world. The project involves three different phases of “power tower” installations in southern California’s Mojave desert. Construction on the facility is still expected to be completed sometime in 2013 and, when it is, the facility should be capable of generating up to 392 megawatts of power. The power from Ivanpah is being sold under separate contracts to Pacific Gas and Electric (PG&E), which gets about 2/3 of the power, and Southern California Edison (SCE), which will take the other 1/3.
